Medicare Cost Calculator
Estimate your total monthly Medicare costs for 2026, combining Part A, Part B (with IRMAA), Part D, and supplemental coverage.
Your total Medicare cost depends on your work history (Part A), your income (Part B, through IRMAA), your drug plan (Part D), and whether you add Medigap or Medicare Advantage. Most people pay at least $202.90/month for Part B plus a separate Part D premium. Enter your details below for a fuller picture.
Medicare isn't one bill, it's several pieces that add up differently for everyone. This tool combines Part A, Part B, Part D, and your supplemental coverage choice into one estimated monthly total, using the same formulas as this site's individual IRMAA and late enrollment penalty calculators.

Total Monthly Cost
Medicare Advantage often has no separate premium beyond Part B, but your actual costs depend heavily on how much care you use, through copays and coinsurance up to the plan's annual out-of-pocket maximum. This tool can't predict that portion — see this site's Medicare Advantage vs Original Medicare comparison tool for more on that tradeoff.
Annual deductibles (context — not part of the monthly total above)
Part A deductible: $1,736 per benefit period (only applies if hospitalized) · Part B deductible: $283/year · Part D deductible: up to $615/year (varies by plan, some are lower or $0)
These are situational costs that only apply when you actually use care — they aren't fixed monthly charges, so they're not added into your total above.
Most people don't pay for Part A at all, since about 99% qualify for premium-free coverage through their own or a spouse's work history. Part B is where income starts to matter: everyone pays at least the standard premium, but higher earners pay more through IRMAA, based on income from two years earlier. Part D adds another variable cost, since plan premiums are set by private insurers and vary by what you're prescribed, plus a potential penalty if you went without coverage when you first became eligible. The last piece is supplemental coverage. Original Medicare alone has no cap on your out-of-pocket costs, so most people either buy a Medigap policy, with its own separate premium, or switch to Medicare Advantage, which usually skips a separate premium but shifts more of the cost risk to copays and coinsurance as you use care. This tool adds up the predictable premium pieces into one monthly total. It doesn't include deductibles, which only apply when you actually use care, or Medicare Advantage cost-sharing, which depends entirely on the care you need.
Frequently Asked Questions
How much does Medicare cost per month in 2026?
It depends on several factors: whether you have premium-free Part A, your income (which affects Part B through IRMAA), your Part D plan's premium, and whether you add Medigap or choose Medicare Advantage. Most people pay at least the standard $202.90 Part B premium plus a Part D plan premium.
Does Medicare Part A really cost nothing?
For about 99% of beneficiaries, yes, if you or your spouse worked and paid Medicare taxes for at least 40 quarters (10 years). Without that work history, Part A costs $311 or $565/month in 2026, depending on your work credits.
Why is my Part B premium higher than the standard amount?
You likely owe an IRMAA surcharge based on your income from two years earlier. See this site's dedicated IRMAA Calculator for the exact bracket your income falls into.
Do I need Medigap or Medicare Advantage in addition to Original Medicare?
Original Medicare alone has no annual out-of-pocket cap, so most people add either a Medigap policy or switch to a Medicare Advantage plan to limit their financial exposure. Which one fits depends on your priorities around cost and flexibility.
Does this calculator include copays and coinsurance?
No, only premiums and the standard annual deductibles are shown. Actual out-of-pocket costs from using care vary significantly and depend on your specific plan and health needs.
What if I don't know my Part D plan's premium yet?

This calculator provides a general estimate of premium costs based on 2026 Medicare figures and does not constitute financial advice. It does not include copays, coinsurance, or Medicare Advantage cost-sharing, which vary significantly by plan and by how much care you use. For your exact costs, check your Social Security benefit statement, your specific Part D plan's pricing, and your specific Medigap or Medicare Advantage plan's terms.
